The invention discloses a control method and device of an electric vehicle, a readable storage medium and the electric vehicle, and relates to the technical field of new energy vehicles. The control method of the electric vehicle comprises the following steps: obtaining the whole vehicle electric power of the electric vehicle, and obtaining the electric quantity ratio between a first battery and a second battery; determining a first preset power corresponding to the first battery and a second preset power corresponding to the second battery according to the electric power of the whole vehicle and the electric quantity ratio; determining a first target power and a second target power according to the electric power of the whole vehicle, the electric quantity ratio, the first preset power and the second preset power; output powers of the first battery and the second battery are respectively set as a first target power and a second target power. The accuracy of the output power of the first battery and the second battery is ensured, the situation of sudden power change of the first battery and the second battery is avoided, and the service life of the first battery and the second battery is prolonged.
